Paul comes to speak of this subject last in his discourse to the Ephesians. God is a God of mighty power and we as believers should always remember we have the right to call on His power and Paul says in reference to the evil of the devil, that we ought “to stand strong in His mighty power.” It is here that he tells Christians, not just Ephesians, to put on the armor of God to stand strong. Putting on the full armor of God will help all of us to successfully stand against the schemes of the devil.
Paul defines the enemy we have: it is not flesh and blood, it is rulers, authorities, powers of the dark world and spiritual forces of evil in heavenly realms.” What does that mean? Who is this enemy of the Christian? We are going to have to think differently, if we are truly want to know our enemy. We think of the people around us who hurt us as our enemies. No, that is not so. It is the spiritual forces behind them that is our real enemy. Satan has a host of evil demons and spirits who follow him and seek to disrupt, destroy and deny the Christian in every way possible, but you can’t see them, just the effects of their evil work.
(An old deacon who used to pray every Wednesday night at prayer meeting always concluded his prayer the same way: "And, Lord, clean all the cobwebs out of my life." The cobwebs were those things that ought not to have been there, but had gathered during the week. It got too much for one fellow in the prayer meeting, and he heard the old deacon one time too often. So when the man made that prayer, the fellow jumped to his feet and shouted: "Lord, Lord, don't do it! Kill the spider!" That's what needs to happen.

Friends, we need to start thinking differently and realize who is behind our temptations and many of our trials and difficulties.
What does Paul say we must do to overcome this evil power that comes against us? It is the armor of God on us, in us and surrounding us that allows us to stand our ground against the enemy. Notice though it is not just one piece of armor but the FULL armor of God! Put on the full armor of God and you will be able to stand your ground against these unseen enemies of the devil.
